Diagnosis. Stomopogon albisetacan be separated from other species by having the entire body covered with many white setae and first hind tarsomere flattened. In addition, it differs from S. hirtitibia, S. paranaensis sp. nov.and S. nigrisquama sp. nov.by the yellow tibiae, and from S. capribarba, S. argentina, S. incultaand S. boliviensis sp. nov.by the yellow postpedicel.
